I remember the days when developers were happy to dish out a Sudoku game with hardly any forethought. The competition for the ultimate logic package is heating up and there are quite a few package deals out there now.

Hands On 3-in-1 Sudoku has the ubiquitous Sudoku as well as Kakuro and Tenpenki. Kakuro is that devilish mathematical puzzle where you have to fill a grid so that the rows and columns all add up to the specified numbers and there are no repeating numbers and is much more mind bending than Sudoku. Tenpenki is apparently an old puzzle game from the East, although we couldn't find any references after a quick internet search. The basics of the puzzle are very similar to PicoPix where you have to use some logic to fill in a grid which will transform in a pretty shape.

Everybody knows what to do when they pick up a sudoku puzzle and it's all about making the mobile experience as pleasurable as possible. Hands On have done a very good job of it. The graphics are nicely drawn and they have gone for a very Japanese theme. The controls for both Sudoku and Kakuro are very similar and offer something different to other games in this genre. The idea of pencil marks has been done before but usually involved cumbersome button presses. The number input this time round is a lot simpler. Press and hold the number button to signify draw a big number and declare it as a 'definite' number. Just tap the number to draw a pencil mark. The pencil marks appear as dots in a 3x3 grid and you can move your cursor over the square to zoom in. Overall, it is a simple and easy to use system.

Tenpenki is still a new phenomenom on the mobile and this version has fairly simplistic controls. As a newcomer to the game, I did thoroughly enjoy it but I was hoping for better quality graphics when it came to the 'reveal' at the end. All three games have four difficulty settings and a number of grid sizes.

What really sets this game apart from other 3-in-1 packages is the sheer number of levels. The game has a 'voyage mode' which is reminiscent of Iplay's Quest series of games. Complete a number of voyages to unlock everything for challenge mode. The voyages will see you take part in a number of games and you do get some choice in the game type (I would personally steer clear of Kakuro - too long winded in my opinion).

The game even stores all your stats and has an online function where you can submit your scores. As a reviewer, it's a bit annonying that there isn't much to fault this game which should mean good news for everyone out there.
